Population dynamics of Townsend's big‐eared bats: effect of age and drought on survival

open access: yesThe Journal of Wildlife Management, EarlyView.
We estimated age‐specific yearly survival of female Townsend's big‐eared bats in Inyo and Mono Counties, California. We found that both juvenile and adult survival were negatively impacted by drought, and that detection probability was lower for hand‐recapture than for bats detected via pass‐through antenna arrays.

Quantifying the cumulative impact of winter habitat loss on a critically endangered migratory parrot

open access: yesConservation Science and Practice
Habitat loss is a major driver of biodiversity decline, often occurring in a slow‐paced, piecemeal way. The cumulative impacts of such loss can be substantial for threatened species but are challenging to quantify and thus factor into planning decisions ...

Statistics, Probability, and a Failed Conservation Policy

open access: yesStatistics and Public Policy, 2019
Many sightings of the Ivory-billed Woodpecker (Campephilus principalis) have been reported during the past several decades, but nobody has managed to obtain the clear photo that is regarded as the standard form of evidence for documenting birds.

Insights from Project FeederWatch: Changes in the abundance and occurrence of birds in New Hampshire over the past 24 years [PDF]

open access: yes, 2014
Changes in the climate and land use over time can lead to changes in the composition of wildlife communities. Using data from Project FeederWatch, we examine trends in the abundance and occurrence of birds documented in the winters from 1988 to 2012 in ...

Environmental and temporal factors affecting record white‐tailed deer antler characteristics in Ontario, Canada

open access: yesThe Journal of Wildlife Management, EarlyView.
Antler characteristics are influenced by a combination of genetics, age, and environmental factors, notably habitat quality and resource availability. In this study, we explored how diverse environmental factors, including climate and land cover composition, affect antler size, tine configuration, and the distribution of record‐scoring white‐tailed ...

Dog attacks on wild desert tortoises: A risk model

open access: yesThe Journal of Wildlife Management, EarlyView.
Domestic dogs attack and severely injure wild desert tortoises at the urban and ex‐urban interface with deserts. Severe trauma to tortoises increased 4 times to shell and limbs and 16.5 times to the gular horn over the decades between the 1970s and 2000s. Tortoises were at exponential risk of severe trauma when living within 12 km of settlements, towns,

Global analysis of annual survival among shorebirds reveals a negative effect of migration distance and a decline in recent decades

open access: yesOikos, EarlyView.
Annual survival is a key demographic parameter driving population trends in wildlife populations. However, despite numerous species‐specific or regional studies, global reviews of the factors affecting the survival of declining taxa remain scarce. Here, we investigated annual survival of fledged immature and adult shorebirds, a globally‐distributed and
